Excellent, thanks!

I haven't had a chance to enable them yet. I also need to update a few other
manual pages under man9 for interfaces that have changed or are obsolete.
Hopefully I'll get a chance to do that later today.

Those are kernel threads, nothing too special about them. For now kernel
threads always run with the big lock held, but that will begin to change
going forward.
If you're interested in seeing some of the effects, you can run the lockstat
command. It will show some of the pressure being taken off the kernel_lock,
and show you how much time is being spent waiting for it. Provided you have
the pseudo device in the kernel, and the device node made you should be good
to go..
spanners$ ls -l /dev/lockstat
crw-r--r-- 1 root wheel 177, 0 Oct 22 16:22 /dev/lockstat
